Heat index values hold particular significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature.
